FRUIT-DRYER.

"LF/ige ctcmtic tuant tu in tgcsc 'iu'tus ntmt mit matting peutl nf ttc time TO ALL Wl-IOM IT MAY CONCERN:

Be it known that I, CHARLES LEAYITT, of Cleveland, in the county of Cuyahoga, and State of Ohio, have inVentedjQ-,ccrtain new and useful Improvements in Fruit-Dryers, die.; and I do hereby declare that the following -isl a fulland complete description of the same, reference being had to the-accompanying drawings, making part .of this speeilicatiemin which#- Figure 1 is a perspective view of the dryer.

Figure 2 is a view of the top. l l

Figure 3 is a transverse vertical section in the direction of the line zx.

Figure 4 is a vertical section in the direction of the line .fd-x.

Like letters of referencerefer to like parts in the different views. A

tA, iig. 1, represents the case of the dryer, which is constructed of wood, and of a size according to thc capacity required. B1ig. 2, is the top, around the sides of which runs a channel or due, C C. The sides ofthe flue C running lengthwise of the case are opened into the interior, whereas the flucs Icrossing the front and rear ends are closed and haveV no communication with the interior of the case, except at the corners at the ends .of the open lues referred to.` Also constructed lengthwise across the centre of the top is a luc, D, communieating at each end with the cross-dues C. 4The side and end ilues, together with the central flue, and their relative connections, are shown in tig. 2, a section of the top being broken away in order thatth-ey may be seen,

-and iii-which figure C is an open side flue C,Vthe closedend flue, and D the central. These open lues are alsoV shown in tig. 3, in which B is the top of the case. On this case it will be observed that the top does not reach across to the sides, but near to it, leaving a short space between the top and sides open to the interior, and which constitutes the open liuc alluded to. On the contrary the top reaches to the ends .of thc case, as shown in lig.

l4:, thuslmaking a closcd'tlue, of which the top of the case forms the bottom; so, also, it forms the bottom of the central flue. Access is had to the interior of the dryer through doors E F G, fig. 1. Immediately below the.

central door is arranged an ordinary furnace, H, of which I I are the outside doors. Connected to this furnace, and reaching back to and through the rear wall of the case, is a heater, J, communicating 'with the outside pipe or chimney K. Y

Having thus indicated the general construction and arrangement of the dryer, the practical use of the; saine is as follows: 'The fruit or other material to bedried is spread upon open or slattcd shelves L, which are then slid into thc dryer or case upon rabbetcd cleats M, arranged one above another, as shown intig. 3. The dryer, on being properly illed with shelves and fruit, is then heated up by the furnace and heater above referred to, the smoke passing ott' through the pipe N to the outside pipe K, while the moisture and other cxhalations of the drying fruit pass up through thc open lues above describcthand are carried by the draught of heated air to the ends of the tlues to the upper corners of the dryer, where they intersect the closed or end lues through which they pass to the central flue D, and from thencethrough the pipe O, to the pipe or chimney K. I By this arrangement of the ilucs it will be evident that the remote upper corners of the dryerv will be heated equally with the more central parts, as the excess of heat will be drawn thereto by the natural draught through thc end lines which open into the dryer at these points, and which are the only outlets. Thus, thc excess of heat and exhalation of the drying fruit escape through common outlets to the outside. Also by thus causing the redundant heat and vapors to pass off around and over the top of the dryer, adds to the heating and drying capacity of the apparatus; hence a less amount of lire is required to accomplish the process of dryinff.

What I claim as my improvement, and desire to secure by Letters Patent, is-

The herein-described arrangement o f the channels or iues C C', and D, in combination with the pipes K I and O, case A, for the purpose and inthe manner set forth.
